Hello Jean-Marc. First of all, thank you for your awesome work on speex! In the current version in SVN the wideband encoder/decoder doesn't correctly pass the parameter of SPEEX_SET_SUBMODE_ENCODING to the underlying narrowband codec. My patch fixes this. Then I have a question regarding the EPIC_48K mode. Should the perceptual enhancer work with this mode? At the moment it is enabled by default but only produces a very loud noise. Finally I would like to ask what your near future plans for the (fixed-point) AGC are. I want to add a speaker phone mode to a PDA based VoIP application and AGC wo...

I've recently applied a few patches to it, but it needs a few more (the enhancer and the LPC window). > Fin...

Running the Male.wav test file, I get all zeros out for the first 5 seconds, then 8 samples ranging from -2 to 2, and then all 0001 samples to the end of the file. I got the same result feeding the encoded bits from Speex version...

Martin Otten did most of the work to get Speex up and running for our games about a month ago, and we just recently released it to the Steam beta. So far it appears to be working pretty well, and we're interested in doing more work using Speex going forward. I'd love to hear any feedback that people have using it, especially at the different quality settings. The information on how it

Hi everyone, I've recently done some major internal changes in Speex aimed at reducing RAM (by nearly a factor of 2!) and improving quality of the fixed-point. In doing so, I might have accidently broken a few things. I'd like to hear feedback on the current svn code to make sure I fix any regression before the next release. I'm already aware that --enable-vorbis-psy is broken and
